CLASSIFICATION AND GRADING OF COTTON.-

To all whoma't may concern:

Be ,it known that I, LEMUEL AUSTIN -GREENE, a citizen of the United States, a

resident. of the city of Greenville and county of Greenville and the State of South Carolina, haveinvented certain new and useful Improvements Pertaining-to Classification and Grading of Cotton. The following specification and accompanying drawing are afull description.

My invention embraces the manner of assembling a series of standard grades of cotton in a cabmet having a transparent cover,

also having nine receptacles for the purpose of containing nine duplicates of the standard grades of cotton now being issued by 0hr Government, embracing the nineleadmg whlte grades of cotton; also nme other receptacles for the purpose of containing the relative tinges of the standard grades of white'cotton. The above eighteen grades are all listed by the exchanges, and each has a specific value on the daily market.

It is also the purpose to have a central receptacle for the purpose of displaying the length of staple.

It is a Well known-fact that different lights or reflections from different walls or buildings, also the bright sun light causes cotton to'appearas adifferent quality or .grade;

. A' cloudy. day,'0r a day When the ground is coveredwith-snovv, will materially affect the appearance of cotton to an untrained eye.

- ;fi-Itirequires long experience and much prac- "ticefona buyer to locate the correct grades 7 of cotton under these and other existing (circumstances.

' It is the purpose of theinventor to ar-' range in a convenient 'mannerthe eighteen '4 0;.

listed grades of cotton embracing the nine standard Government grades in a cabinet under a transparent cover for the protection of the fixed grades while in use, and not interfere With the 'work of matching any or any change of light or reflection, because sample of cotton under any circumstances \the same reflections are alike on the fixed -grades and the sample. to be graded. It is 'not'possible for the cotton growers to become expert cotton graders, because the minds eye cannot maintain these reflections ofcolor. and leaffor lack of continual practice, as is the casewith a cotton buyer.

Application filed April 30,1917. Serial No. 165,602.

Figure 1 is top plan view of my invention.

Fig. 2, is a central, vertical section of the grader taken on the line ,2-2 of Fig. 1; and

Fig. 3 is a bottom plan view.

The outer casing is formed by two concenlZI'lC circular rims, 1 and 2, preferably 24: v

and '18 inches, respectively, in diameter,

connected by an annular plate 3. The second inner casing is formed by two smaller rims, 4 and-5 preferably 12 and 4: inches in diameter, respectively, concentric withthose first named and with each other and connected by an annular plate 6. Nine equally angularly spaced radial ribs 7 connect the innermost with the outermost rims, thereby dividing the zone formed by the rims -1 and- -2 into nine compartments, 8, that by the rims 2 and 4 into nine compartments, 9, and that by the rims 4 and 5 into nine compartments, 10. The inner circular rim 5 forms the wall of ac'entral compartment 11 into 'Which. telescopes a removable bottom 13.

The glass plate 12 is superposed upon the parts thus constructed, which are preferably made of paste board. 'This plate 12 protects the contents of the grader from being injured by usage, and from dust and other sources of damage.

v The outencompartments-8 are adapted to receive the duplicates of the nine Govern-' ment standard grades of cotton. The mates of these official grades, found in the tinges tacle 9' and compared with'the'samples in the compartments 8 and 10.

Having describedmy invention: what I claim as new and desire to secure by Letters 'of Patent is:

1. A cotton classifier consisting of a case provided with a plurality of compartments adapted to receive samples of cotton, said compartments being divided into two equal series, separated by a space permitting the viewing therethrough of samples to be 'sting of a case 2. A cotton classifier-con provided with a plurality of compartments divided into two equal circular series separated by a space permitting the, viewing tlieretlirough of samples to be classified and acentral pocket about which the two circular series are arranged.

'3. A cotton classifier eonsisting'of a case provided with a plurality ofcompartinents adapted to receive samples of cotton, said 10 compartments beingflllivided into two equal circular series, separated by a space permit ting the viewing tlieretlirough of samples to be classified.

In testimony whereof I afiix my signature in presence of two witnesses, this the 24th 15 day of March, 1917.
